Need another hint

[nancygevans]

Thanks for the last hint, I was able to proceed. Now I'm in room 19100 with a yellow key but nowhere to go. How do I proceed from here? Thanks for a great challenging mansion!

hint in white: go back to the right. This is a dead end

[nancygevans]

Thanks Olle but where do I go to the right to proceed? I can't find any new avenues.

Go back to someplace you've been before

Hint: someplace where there's a sign saying it's a

dead end
